This reverts commit 2507c7170443cf4cced4d2cda8ba3c8cc259adb1. Why crowd up search-paths for the normal native compiler with all sort of invalid stuff. Why -UCONFIG_TRIPLET if it isn't set at all for cross-compilers. Also, the patch still didn't do anything useful "out of the box". Instead I'd suggest to do something more simple and more effective. See Makefile: - set search paths for cross-compilers to /usr/<triplet> by default - Install any built "xxx-tcc" and "xxx-libtcc1.a", even if not listed with PROGS_CROSS/LIBTCC1_CROSS - Support ELF-<target> = ... to set the elf interpreter Some common gnu-triplets are supported by default TRIPLET-i386 ?= i386-linux-gnu TRIPLET-x86_64 ?= x86_64-linux-gnu TRIPLET-arm ?= arm-linux-gnueabihf TRIPLET-arm64 ?= aarch64-linux-gnu TRIPLET-riscv64 ?= riscv64-linux-gnu Other triplets can be given explicitly, for example like this: $ make cross-arm-eabi TRIPLET-arm-eabi=arm-linux-gnueabi $ sudo make install
